Ectopic atrial tachycardia originating from right atrial appendage aneurysms in children: Three case reports
Introduction Ectopic atrial tachycardia occurs at a rate of 5%–20% among children with supraventricular tachycardia. Atrial appendages are the most frequent focus in children, differing from the situation in adults. However, ectopic atrial tachycardia originating from aneurysms of the right atrial appendage is very rare and in fact has not yet been clearly defined. We describe 3 cases of childr...
متن کاملSuccessful catheter ablation of focal left atrial tachycardia originating from the mitral annulus aorta junction.
Focal left atrial tachycardias (AT) originating from the mitral annulus-aorta (MA-Ao) junction are rare and their mechanisms are unclear. We report a 35-year-old male with successful ablation of an exercise-induced focal AT due to triggered activity originating from the MA-Ao junction. The AT occurred spontaneously during treadmill exercise testing and was easily induced by an atrial extrastimu...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
متن کاملEpicardial Ablation of Focal Atrial Tachycardia Arising From Left Atrial Appendage in Children
Focal left atrial tachycardia (FLAT) although a common cause of supraventricular tachycardia(SVT) among children, the one's arising from left atrial appendage (LAA) present a unique challenge for successful ablation because of anatomical location. We present two children with FLAT arising from the epicardial LAA, successfully mapped and ablated through percutaneuous epicardial approach.
متن کاملLarge thrombus originating from left atrial diverticulum: a new concern for catheter ablation of atrial fibrillation.
A 45-year-old man was admitted to our hospital for evaluation of a left atrial (LA) mass. The patient had a history of dilated hypertrophic cardiomyopathy, atrial fibrillation (AF), diabetes mellitus, and sustained ventricular tachycardia that was treated by implantation of a cardioverter-defibrillator. He had developed AF 1 year earlier and was followed up at the outpatient clinic. He had been...
